Wall insulation is a way of saving energy while enjoying maximum thermal comfort. There are many different types of wall insulation. Faced with all these alternatives, you may feel a little lost. To help you make the right choice, it’s important to bear in mind that costs, time and energy savings, and insulation methods all count. Here are a few points to help you make the best choice.
Spend less with internal wall insulation
Insulating walls from the inside is one of the most common techniques used in France. More economical, it offers the advantage of lower heating bills. Indeed, the key role of wall insulation is to ensure that you live in a pleasant home all year round. You won’t need to stay away from the walls for fear of catching a cold, especially with winter fast approaching. On the other hand, interior insulation is also acoustic insulation.
It will considerably reduce noise and disturbance from outside, especially if you live in an urban environment or near public thoroughfares. Numerous professional websites offer offers for the installation or sale of wall insulation materials. You can also obtain information by following the explanations of isolation-info.fr online. This website will keep you up to date with the latest news on internal, external and cavity wall insulation.
A variety of interior insulation methods are available. Choose the one that’s best for you and your needs.
Applying panels or blocks
Using glue or dowels, panels or blocks are applied directly to the wall. Since insulation from the inside has the bad reputation of reducing living space, this method means you don’t have to reduce it too much. All you need to do is check that your wall is compatible with the insulating complex.
Sprayed insulation
Sprayed insulation is highly recommended for walls with uneven surfaces. The insulation is applied directly to the wall, giving it a flatter, smoother appearance. Cellulose wadding is generally the most widely used insulation for sprayed insulation.
Wood or metal frame application
If you choose to insulate from the inside, our experts will advise you from the outset to use wood or metal framing. Framing is also ideal for walls with major defects or which cannot withstand the application of direct insulation. Insulation – semi-rigid boards, rolls, poured or blown loose insulation – is inserted into the framework. They are then covered with a vapour brake and fixed to battens.
The choice of insulation depends on your needs, your preference and your insulation technique.
Insulate cavity walls with polyurethane foam
Considered the quality par excellence, polyurethane foam insulation is ideal for cavity walls. This is a double wall consisting of an outer wall and an inner wall, with a void of a few centimetres in the middle. Thanks to polyurethane foam‘s micro-bubble air system, it’s hard for heat to escape and cold to enter your home. Your comfort will depend on the thickness of the foam.
According to the experts, an insulation value of between 0.025 and 0.027 W/m2K is best. Here, the number of thicknesses of polyurethane foam is far superior to other forms of insulation. A cavity wall will thus be filled in harmony with your comfort.
As the foam is generally applied as a liquid, it will harden into a solid form. It will then cling tightly to the walls, leaving no room for small openings. The greatest advantage of polyurethane foam insulation is its total respect for the environment and the human body.
We all know the extent to which the products used to optimize our everyday comfort are damaging the ecological balance. Fortunately, foams don’t fall into this category. They contain no toxic or irritating elements, no odors and no volatile compounds. Once you’ve installed polyurethane foam insulation, you’ll enjoy a soft, calm atmosphere.
Think big with external wall insulation
When you choose to insulate your walls from the outside, you’ll have the full living space of your home at your disposal, with the added comfort of warmth. Your home will also be eligible for various ecological grants, local grants and energy allowances. These grants cover up to 70% of the cost of the work. The reason for the grants is simple: the installation of insulation visibly reduces energy consumption.
Insulation under plaster
Customizable, you can paint undercoat insulation in the color you prefer to match your home. It’s also considered the least expensive form of exterior insulation. The technique is simple: large panels of insulation are glued or screwed to the facade of your home. You then cover with organic or hydraulic underlay to reinforce the walls. Once this is done, you apply the plaster in the color of your choice.
Insulation under cladding
Like framed insulation, cladding insulation also requires a metal frame. It can be adapted to any type of surface, and will correct any defects or irregularities in your walls. We recommend it if you have damaged or damp walls.
The insulating panels are fixed to the metal framework and then covered with cladding. This is the type of insulation where the appearance of your home will change the most, and where you’ll need administrative authorization for the work.
Every insulation technique has its advantages and disadvantages, whether you choose to insulate from the inside, outside or using cavity walls. It all depends on your budget and your needs. It’s up to you to find the best solution for your situation. In any case, insulation saves energy and brings greater comfort, especially in winter.
